I have a frigidaire laundry center that is less than two years old. The washer threw the belt a few months ago. I put it back on, but noticed the drive pulley has cut into the back of the plastic wash drum. It recently threw the belt again. I put it back on only to have it throw it off again. This time the belt needed to be replaced. I put the new belt on and it will not stay on. It slips off as soon as the drive pulley engages. It is not making any noise with the exception of hearing the drive pulley scrape against the drum and the wash drum spins freely by hand. Would bad bearings cause this? If so is this a complex repair. I am somewhat mechanically challenged. If I have to have a repairman come out how much should I expect this to cost?
